Pressure stabilizing device for engine cooling system

Abstract

The invention provides a pressure stabilizing device for an engine cooling system, which comprises an engine water cooling circulation pipeline, radiating fins and a main water tank, the top end of the main water tank is communicated with an auxiliary water tank through a pressure relief pipe, and a pressure pipe communicated with the pressure relief pipe is arranged on one side, close to the main water tank, of the pressure relief pipe; a control assembly used for controlling the internal pressure value of the main water tank is arranged in the pressure pipe. According to the scheme, the accuracy of pressure relief can be more accurately controlled, it is guaranteed that the pressurizing hole can be accurately located in the pressure relief pipe, meanwhile, the sliding groove and the limiting column can accurately enable the pressure relief hole to be located in the pressure relief pipe, the service life of the water tank pressure relief device is effectively prolonged, pressure relief of a water tank is more accurate, and it is guaranteed that under the relatively constant optimal pressure, the pressure relief effect is better. And the cooling efficiency of the engine is improved to the maximum.

Description

technical field [0001] The invention relates to the technical field of engine cooling systems, in particular to a voltage stabilizing device for the engine cooling system. Background technique [0002] The heat generated during the working process of the engine needs to be exchanged by the cooling system. The most common cooling system is the water-cooling system, which uses the coolant circulation in the water-cooling system to bring the heat of the engine to the heat sink, and blows air to the heat sink through the fan of the engine. To cool down, the cooled coolant re-enters the engine for heat dissipation circulation system; the coolant is in the water tank and the circulation pipeline, and the water tank is provided with a water tank cover for regular filling of coolant. [0003] For example, the application number is CN02247839.6, which discloses a forced pressure relief and anti-scalding water tank cover. At present, the water tank cover on the water tank has the func...

Problems solved by technology

[0003] For example, the application number is CN02247839.6, which discloses a forced pressure relief and anti-scalding water tank cover. At present, the water tank cover on the water tank has the function of adjusting the pressure of the coolant in the water tank, and can adjust the cooling hydraulic pressure in the water tank in time. However, the sealing part of the current water tank cover is made of corrosion-resistant rubber material, and the deformable characteristics of rubber are used to open and close the seal. service life

[0004] At the same time, the water tank cover is provided with a spring with a fixed compression force, and the cooling liquid inside and out of the water tank is controlled by the preset spring compression force. When the cooling liquid is discharged to the outside, it is discharged through the circumferential edge of the rubber pad, which is consistent with the spring. The force between them is non-radial, so the spring is not accurate for controlling the pressure of the coolant in the water tank, it is difficult to control the preset pressure value of the coolant, and the best cooling effect of the coolant cannot be guaranteed.

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
